FREE TX CDL General Knowledge Marathon 2019

Need a final study-spree? This Texas CDL General Knowledge Marathon is a massive study tool that contains all 380 questions from our database for this TX endorsement. If you select a wrong answer, we’ll remember that question and will display it to you again at the end of the exam until you’ve answered that question correctly. In other words, the Marathon will cycle through your missed questions until you answer each one correctly. You must make a 100% to pass. We suggest you attempt this one after you have practiced the state’s “regular” tests, but before the “Exam”. Give it your best shot!
